I have a request from our security team to write a filter to quarantine or block email with a couple conditions including what the dmarc result is. The email is from a domain that is currently p=none. Wondering if I can use the dmarc result in a filter along with the envelope sender and from address. If not, is there a way to add an x-header with the dmarc result I could perhaps key on in an Exchange Transport rule.
Thanks for any help.
